Why this tool is useful
Rainbow Flow produces a smooth continuous cycling of the full color spectrum across your screen in a flowing gradient animation. Unlike the rapid flicker mode, Rainbow Flow transitions slowly through hues in a calming looping wave pattern. It is used in creative office spaces, photography studios, and streaming setups as an ambient background light source. The slowly shifting hues provide dynamic naturally varied colored illumination that is photographically interesting without the disorienting impact of rapid color changes.
